The earth is the home on which human beings live, modern science believes that our earth was born 4.6 billion years ago, that is, the early days of the birth of the solar system, scientists have calculated that the sun was born 5 billion years ago, the sun after birth absorbed a large amount of material around, so the mass of the sun is the most massive celestial body in the solar system. Its mass accounts for 99.86% of the total mass of the solar system, and the remaining eight planets and other materials account for 0.14% of the total mass of the solar system, from the proportion we can see that the mass of the sun is very large, there are eight planets in the solar system, they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
In the eight planets, only the earth was born with life, the emergence of life to the earth of this planet added a lot of color, especially the emergence of human beings, unlocked a lot of mysteries on the earth, if human beings do not appear, then the mystery of the earth may never be solved, after the birth of human beings began to continue to explore the mysteries of the world, through the study of scientists we can know that the reason why the earth can give birth to life is mainly because the earth meets the three basic conditions for the birth of life, These three basic conditions are suitable temperature, sufficient air and abundant water resources, and if other planets can meet these three basic conditions, then the possibility of life on other planets is very high.
Among the eight planets, Mercury is the closest planet to the sun, because Mercury is very close to the sun, so the water on the surface of Mercury has been evaporated, without water resources it is impossible to give birth to life, so the significance of human exploration of Mercury is not very large, behind Mercury is Venus, Venus and The earth are called sister planets, because the mass and volume of Venus are similar to the earth, but scientists after exploring Venus found that it is impossible to give birth to life on Venus, why say so? Because the temperature on the surface of Venus is as high as more than 400 degrees Celsius, such a high temperature can not survive any life, and the content of carbon dioxide in the atmosphere of Venus is very high, basically the atmosphere of Venus is carbon dioxide, so there will often be acid rain on Venus, from the various conditions of Venus, Venus does not have the conditions for the birth of life.
Mars is a planet relatively close to the earth, scientists through the study of Mars found that Mars has no magnetic field, because Mars has no magnetic field, so Mars has become a desolate planet, outside of Mars is Jupiter and Saturn, because Jupiter and Saturn are two gaseous planets, there is no place to stay, so it is impossible to give birth to life, behind Saturn is Uranus and Neptune, because these two planets are far from the sun, so the surface temperature is very low, liquid water exists in the form of ice, Among the eight planets, the only planet that has the conditions for transformation is Mars. Musk, a well-known entrepreneur, spoke about his new goals at Tesla's 2021 shareholder meeting.
He hopes that he can build a factory on Mars before 2050, many people may feel incredible, in fact, Musk proposed the Mars immigration plan in 2015, for this plan he also made a lot of preparations, many people may think of Tesla as soon as they hear Musk, in fact, Tesla is just one of his companies, there are many companies under Musk, such as SpaceX, this company is mainly developing spaceships, The company's spacecraft is equipped with 37 of the latest Raptor engines, which has no problems in terms of power, and a spacecraft can transport more than 100 tons of supplies at a time.
In addition to this company, he also owns SolarceX (Sun City), Starlink (satellite interconnection company), TheBoring Company (a company that solves traffic congestion), Hyperloop (Hyperloop company), OpenAl (artificial intelligence), Fyture of life institute (Life Future Institute), etc., we can see from the names of these companies. These companies are all linked, it can be said that this is a complete set of immigration plans, no wonder Musk can be so confident, but it is not an easy task to transform Mars, at present, Mars does not have a magnetic field, magnetic field is very important for life.
Our earth has a strong magnetic field, the magnetic field can resist solar storms, and can also firmly grasp the atmosphere is not blown away by the solar wind, if there is no atmosphere, then the ultraviolet rays of the sunlight will directly hit the skin of the organism, causing harm to life, it can be said that there is no magnetic field, there is no atmosphere, life without the atmosphere can not survive for a long time, and Mars has no magnetic field, so there is no atmosphere on Mars, if you want to colonize Mars, you must solve two problems, the first is to let Mars have a magnetic field, The second is to let Mars have an atmosphere, Musk believes that the Martian atmosphere can be modified, he believes that bombing the poles of Mars with 10,000 nuclear bombs, which can produce a large amount of carbon dioxide, thereby increasing the concentration of the Martian atmosphere.
However, scientists believe that this way can only enhance a small part of the Martian atmosphere, want to make the Martian atmosphere become the same as the Earth, basically impossible, and even if it can make Mars have an atmosphere, if there is no protection from the magnetic field, then the Martian atmosphere will disappear, see here may be many friends will have a question, that is, how the magnetic field is generated? Scientists speculate through research that the Earth's magnetic field was formed in the early days, in the early days of the solar system, the solar system is very chaotic, often there will be asteroid impact on the Earth scene, although the asteroid hit the Earth, but also a large amount of metallic material left on the Earth, these metal materials through the Earth's crust movement for hundreds of millions of years, and finally sink into the core, and then the Earth has a magnetic field.
So, want to make a planet have a magnetic field, is not an easy thing, now with human technology to completely transform Mars is impossible, in addition to we can build a completely closed ecological environment on Mars, in this ecological environment, human beings can live, but even so, also need a lot of human, physical and financial resources, and the transformation of Mars requires large machines, how can these large machines be transported to Mars? This is a question worth thinking about, but now there are more than 20 years away from 2050, and maybe in more than 20 years, human technology can be greatly improved, and it will no longer be difficult to immigrate to Mars.
Although Musk's idea is very crazy, but I have to say that Musk is indeed an entrepreneur with ideas, and he has begun to work hard towards his new goals, Xiaobian hopes that in 2050, we can take a spaceship to Mars to travel, interstellar migration human future must take the road, after all, the earth's resources are limited, and the earth's environment is getting worse and worse, if the long-term development continues, then human beings will definitely immigrate, but human flight speed is very slow, Even the solar system can not fly out, so can only choose from the planets in the solar system, if the future human flight speed can be greatly improved, then maybe we can fly out of the solar system and find a new home, in this regard, do you think Musk's 2050 Mars colonization plan can be realized?
